Application The invention relates to nozzles and more particularly to nozzles designed for use with hose of The invention has for its object to provide a nozzle of the, indicated class which is simple in construction and of maximum eiiiciency in operation.

Another object of the invention is to provide a novel nozzle having a minimum of partsand in which undesirable leakage is positively and efficiently avoided.

The invention contemplates further the provision of a nozzle which may be controlled and regulated without effort to provide issuing streams of water or its equivalent of `varying characteristics and particularly streams in which the water is atomized and reduced to a fine mist.

A further object of the invention is to provide a novel nozzle in which the component parts are capable of being made of plastics to produce an efficient and easily operated arrangement.

Other objects will appear from the description hereinafter and the features of novelty will be pointed out in theclaim.

In the accompanying drawing, which illustrates examples of the invention without defining its limits, i

the type exemplified by conventional garden hose. i

Fig. 1 is a central longitudinal section of the A novel nozzle in one form;

Fig. 2 is a cross-section on the line 2-2 of Fig. 1;

Fig. 3 is a central longitudinal section of the controlling and regulating cap of the nozzle, and

Fig. 4 is a central longitudinal section of the novel nozzle in another form. i

The nozzle comprises a tubular body preferably of cylindrical form and consisting of a cylindrical section 5 having an externally-threaded section at its one end, and a continuing preferably cylindrical section 'I projecting from said threaded section in axial registry with the section 5.

A converging, preferably conical head 8 projects from the section I in an axial direction and at its base is of less exterior `diameter than the section 'I so as to form an annular shoulder 9 at this point. The outer surface of the conical head 8 is perfectly smooth and even for the purpose to be more fully set `forth hereinafter. A preferably cylindrical stem IU extends from the conical head 8 in axial outwarddirection and terminates in a boss Il having an annular lower edge which preferably is beveled as shown at I2; as shown, the upper surface of the boss II may converge towards the center to form a conical apex.

As shown, the tubular body includes an axial channel or bore consisting of "a section I3 and a continuing section I-'i of reduced diameter to form an internal annular shoulder l5 at the point of connection of the two channel sections as illustrated in Fig. l. The `channel section I4 terminates in and communicates with diverging outlet September 9, 1944, Serial No. 553,334 i oaim. (ci. 299-131) channels I6 located in the conical head 8 and having their exitends located at the outer surface thereof. In the preferred arrangement the outlet channels I6 themselves each diverge toward their exit ends,.with the upper surface portions I'I of said channels I6 extending at steeper angles than the lower surface portions thereof, and forming an interior relatively sharp point or apex I8 in registry with the channel section I4.

At asuitable intermediate point the body sectionV is `preferably provided with an annular surface groove for accommodating a packing gasket I9 secured in place in any convenient manner. i

In addition to the parts so rfar described, the nozzle includes means for controlling the flowof water therethrough and for regulating the type and character of the outiiowing stream.

In the illustrated example the controlling means comprises a cap 20 mounted in lthreaded n engagement with the section 6 of the body section 5 for e rotatable adjustment thereon. As shown in Figure 1, the threaded portion of the cap is of greater axial extent than the section 6, extending beyond both ends of the section 6 when the cap is fully closed. The cap- 20 includes an internal cylindrical section having a straight, even surface 2 I, and dimensioned to rotatably t upon the body section 'I. In addition, said cap `ZIiis provided internally with a converging or conical surface 22 dimensioned and arranged to snugly Yfit the outer surface of the conical head B, when said cap 2i! is in its closed position. At its base, the converging or conical surface 22 terminates at an internal annular transverse shoulder 23 extending between the surfaces 2| and 22, as shown in Figs. 1 and 3. A preferably cylindrical surface extends axially outward from the conical surface 22 to constitute an axial passage 24 ter# minating in a flaring exit end 25 opening in the outer end face of the capas illustrated in Figs. 1 and 3. The diameter of the passage 24 is such as to loosely accommodate the boss I I and stem lli as shown in Fig. 1.V

In the fully` closed positionof the` nozzle,` the i cap 2B is screwed down upon the section 6 until the surface 22 is in firm surface engagement with the outer surface of the conical head V8 which projects into the cap passage 24. At this stage, the exit ends of the outlet channelsV I6 are covered by the cap` 20 and sealed by -the engagement of the cap surface 22 with the surface of the conical head 8. Both of these surfaces are smooth and contact with each other throughout to provide a watertight closure and seal whereby the nozzle is efficiently closed against' the exit of water or its equivalent therethrough. i Leakage is prevented by the single gasket I9 which is in sealing engagement with the cylindrical surface 2| of the cap 2U. Complete closure of the nozzle is effected, however, by the` surface` 22 of the cap 20 in association with the surface of the conicalihead 8.

To open the nozzle, the cap 2B is rotated on the threaded section E5 in a direction to shift said cap outwardly and thereby adjust the surface 22 out of contact with and away from the outer surface of the conical head 8.

`This unseals the exit ends of the outlet chan'- nels IG and enables water to pass therethrough from the axial channel i3, i9. As the water passes through the outlet channels l0 it is diverted thereby and particularly by the surface portions I 'l and apex i9 thereof in the form of diverging streams, in opposite directions against the conical surface 22 of the cap and along the latter in a converging stream toward the axial passage 24. The water, in a confined stream, passes along the conical surface 22 and through said axial passage 24 into contact with the beveled annular lower edge l2 of the boss Il. The stream of water will accordingly be divided into a mist or atomized and spread to an extent de,- pendent upon the location of the aring exit end 25 of the 'passage 2li relatively to the boss il. This relationship will determine the spread of i Vthe water passing out through the nozzle as will be apparent. If the adjustment of the cap 20 is such as to bring the exit end 25. of the passage 24 outwardly beyond the boss l l, the water will flow from the nozzle in a substantially solid stream spread only to a degree determined by the iiare of said exit end 25. At all of these stages, the packing gasket E9 prevents undesirable leakage back through the cap 29.

The nozzle is provided with coupling means for connecting the same with a hose, which means may be of any suitable type or which may comprise the novel device shown and forming the subject-matter of another application led by me.

The illustrated coupling means includes a hollow body 26 having a surface opening 2 8 and' provided interiorly with axially spaced bearing surfaces 29 and 39 for developing an axial clamping action on heads 3l and 32 respectively. The-latter form part of a stem 33 secured in the end of a hose 34 by means of a sleeve 35Y andassociated elements.

The form of the novel nozzle shown in Fig. 4 corresponds in construction and operation with the nozzle illustrated in Fig. 1, and differs therefrom only in the type of coupling means whereby the nozzle is connected with a hose.

In the form -now being described, the body section 5 is provided at its free end with an externally-threaded upset portion 35 for the threaded accommodation of an internally-threaded sleeve 31; A stem 39 projects axially from the boss 36 and terminates in a preferably rusto-spherical head 39, it being understood that an axial passage extends through the head 39, stem 38 and boss 39 into communication with the channel section i3 of the nozzle.

This coupling means is connected with the hose 4i by forcing the head 39 and stem 38 into the end thereof until the end face of said hose engages the face of the boss 30. The sleeve 31 is then adjusted into contact with the outwardly bulged portion of the hose 4i to co-operate with the head 39 and stem 33 in xing the nozzle securely in connection therewith.

The nozzle, in all of its novel forms, is easily operated with a minimum of effort to control the water at will and to vary the character of the outowing stream in a manner to provide the most eiiicient results dependent upon the use to which the associated hose is put.

The novel nozzle is specially adapted for use with garden hose for watering purposes, and may be constructed of any suitable material. The novel nozzle is specially adapted to be made of suitable plastics and avoids the necessity for complicated packing to prevent leakage.

Although the present invention has been described in conjunction with preferred embodiments, it is to be understood that modifications and variations may be resorted to without departing from the spirit of the invention, as those skilled in the artwill readily understand. Such variations and modifications are considered to be within the purview and scope of the clairn,l
